REGENERATIVE COKE-OVEN.

Specification of Letters Patent.

Application'led February 11, 1910, Serial lNo. 543,235.

To all whom it concern.'

Be itlrnoivn that I, JEAN GERAR-n'Kiios, a

subject ofthe Dutch Queen, and residing atv Essen-Ruhr, Germany, haveinvented certain neiv'and usefullmprovements in Regenerative Coke-Ovens,ofwhich'the following is a specification.

This invention relates "to colreovens ofthe regenerative type, in whichth'e5 Waste gases are utilized to heat the air 'supplied for fuelcombustion. i

The objects of the invention are simplicity of construction, economy ofheat and saving in labor of manipulation. i

One illustrative embodiment of the inventionis represented by Way ofexample in' the acompanying drawing, wherein Figure 1 is a longitudinalsection through a retort or coking chamber,- and Fig. 2' is a likesection through a heatingwall of ,the

Fig. 4 a cross-section on the plane C-D, and Fig.,5 a'cross-,section'oii the plane E-F in Fig. 1.

The same reference characters indicate corresponding 'parts in thedifferent figures.'

The drawings represent av bench or battery of celte ovens embodying thisinvention.A

This bench conta-ins seven' coking chambers relation, inclosed and thisclass of ovens. are provided With combustion chambers b ,and .Withhorizontal flues f'above s'aid com being connected bustion chambers,eachiiu' -With the combustion 'chamber below it by openings-b in the top-of the said chamber. .Descending lfines g connect the fluesf withhorizontal fines gj Awhich extend along 4the benchat one sidethereof. yA single regene'ifator -is y each coking chamber a and connected bylateral channels extending in opposite directions to the combustionchambersof the opposite. sidewalls oi said coking chamber.

Ahorizontal v.Waste gas flue. 12 extends along the top of theregenerating chamber and. is vconnected at one end With the exhausttlues of the combustion chambers and at the other end with lsuoliregenerating chamber. horizontal hot air`distributing flue 13 isdisposedover the heating flue 12 and connected atv one end :with-,theregenerating chamber and provided-With a series of exit openings 1.3along its rtop. A hot air feed chamber 14 is disposed over`said*distributingflue 13 and underneathrthejcoking chamber. The exitopenings 13. extend from the top of the 'distributing duel?) into thebottom of. the feed chamber This feed chamber 14 is provided' withlateral vchannels b2 connect- -ing with-'the combustion chamber b in the.heatingwal'l to theleft and' with lateral channels b3 connecting thecorresponding combustion chamberV c 'in the heating Wallat .the right.The openings 1.3 into the feed .chamber-14 are' disposed atintervalspreterably opposite the spaces between the lateral exhaust channelsb2and b3. yThis arrangement of the flues and 'their connecting chanto theseveralvconibustion chambers-'and Vsecures a continuous operationWithout rreversal of draft. 5A channel 15 connectsone wend oftheregenerating chamber r with an channel o, a branch of the channel 15;serves as an airV inlet for said chamber.. .-Mvalve lzy'servesto openthe channel oand close the channel 15 or the reverse.

The valve h2 controlscommunicationbetween said tlues g and 12. rlhis valve is' operated inconjunction with the valve Zh The. valve 7c? serves to controlcommunication at the opposite end of the flue 12 with ,the flue 13. Asshown in Fig. 1 the valves 7a2, Z2 and Zig are arranged forutilizingfthe regenerating chamber which has been previously omitted,for heating the fresh air admitted through the inletvo, the currentthereof taking the direction of the arrows in the vthird figure. llVhenthis regenerating chamber is to be heated the valve h2 is opened, thevalve Z2 is shifted to close the'inlet 02 and to open the channels 15and the valve 7a2 closes the communication between the horizontal dues12 and 13. In such case the Vproducts of combustion from the heatingwalls pass along the flue f at the top thereof, thence downward throughthe vertical flue g, thence into the horizontal channel 7, thencethrough the valves 71.2 into the horizontal flue 12, thence downwardthrough the vcrtic'al channel 17 and opening 16 into the regeneratingchamber d. In passing through this chamber d the gases heat said chamberto the proper temperature and pass out through the Vchannel 15 to thelarge flue z' leading to the chimney.

The dampers 7c and ZJ correspond with the dampers 7a2 above described,the damper's h and it correspond with the dampers h2 above described;and the dampers Z and Z3 correspondV with the damper Z2 above described.The dampers 702162 and k3 are preferably connected with a shaft m at oneend of the b ench, and the dampers h', h2, h3, Z2 and Z3 are preferablyconnected with a shaft n at the opposite endv of the bench, these shaftsbeing located longitudinally of the bench but transversely of thefurnaces therein and when operative to open and close simultaneously thevalves connected with them respectively. IThe regenerators at oppositeends of the bench have connections with one coking chamber only as shownin the aggregated Figs. 3-5. The gas may be supplied through a pipe 20having jets 2 entering channels 25 having openings 2 into channels 30having openings 31 into the combustion chamber (Z. tion secures acontinuous passage of the heating gases through the heating walls in thesame direction avoiding reversal of the drafts and complexity of4regenerators.
